[0003] A complete POE system consists of two parts: the Power Sourcing Equipment (PSE) and the Powered Device (PD). The PSE provides power to Ethernet client devices and manages the entire POE power supply process. The PD, on the other hand, receives power from the PSE and serves as the client device of the POE system, such as an LED smart lighting system or an LED positioning system.

[0038] If the interface data signal rate is greater than the preset transmission rate, the signal rate control unit transmits according to the current interface data signal rate;

[0039] When the voltage conversion unit receives the input signal, it converts the input signal according to the Ethernet signal standard and transmits it to the Ethernet signal output unit.

The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] See also Figure 1 , which is a schematic structural diagram of a PSE device based on multimodal energy and signal input in a first embodiment of the present invention, includes a multimodal power supply module 10, a PSE module 30, and a communication module 20, wherein:

[0048] The multimodal power supply module 10 is used to power the PSE module 30 and the communication module 20. The multimodal power supply module 10 includes a first power supply unit 101 connected to the third-party energy 60 and a second power supply unit 102 connected to the mains. In this embodiment, the third-party energy 60 mainly refers to other forms of energy such as water energy, wind energy and light energy. The first power supply unit 101 specifically includes a third-party energy conversion subunit 1011, a charge and discharge control subunit 1012 electrically connected to the third-party energy conversion subunit 1011, and an energy storage subunit 1013 electrically connected to the charge and discharge control subunit 1012. The energy storage subunit Unit 1013 is electrically connected to the PSE module 30 and the communication module 20 respectively to supply power to the PSE module 30 and the communication module 20 respectively through the energy storage subunit 1013. The charge and discharge control subunit 1012 is electrically connected to the second power supply unit 102, wherein the third-party energy conversion subunit 1011 is used to convert the third-party energy into electrical energy. The charge and discharge control subunit 1012 is used to monitor the power of the energy storage subunit 1013 and control the third-party energy 60 and / or the mains 70 to charge the energy storage subunit 1013. By setting the third-party energy 60 for power supply, the load of the mains power can be saved.

[0049] Furthermore, the second power supply unit 102 includes an AC conversion subunit 1021, a mains complementary control subunit 1022 and a DC-DC boost subunit 1023. The input end of the AC conversion subunit 1021 is connected to the mains 70 and is used to convert the received AC power into DC power; the mains complementary control subunit 1022 is also electrically connected to the AC conversion subunit 1021 and the charge and discharge control subunit 1012 respectively, and is used to control the AC conversion subunit 1021 to turn on when the third-party energy 60 generates insufficient power, so as to control the mains 70 to charge the energy storage subunit 1013, that is, the PSE device in the scheme is set to be powered by the third-party energy first, and only when the third-party energy supply is insufficient will it be powered together with the mains; the DC-DC boost subunit 1023 is electrically connected to the mains complementary control subunit 1022, and is used to boost the mains voltage output by the AC conversion subunit 1021 to convert it into a 48V DC voltage that meets the PSE device power supply standard.

[0050] By way of example and not limitation, the charge and discharge control subunit 1012 is a charge and discharge controller, the energy storage subunit 1013 is a battery, and the AC conversion subunit 1021 is an AC to DC switching power supply.

[0051] Furthermore, while implementing multimodal power supply for the communication module 20 and the PSE module 30, the communication module 20 also supports multimodal network communication. The communication module specifically includes a third-party signal detection unit 201 and an Ethernet conversion unit 202, wherein the third-party signal detection unit 201 is connected to the third-party signal input unit 90 and is used to receive the third-party signal sent by the third-party input unit 90 and detect the signal type of the third-party signal. The Ethernet conversion unit 202 is electrically connected to the third-party signal detection unit 201 and is used to retrieve the corresponding interface standard according to the signal type of the third-party signal and convert the received third-party signal into an Ethernet signal according to the interface standard corresponding to the third-party signal. It should also be noted that the third-party signal input unit is electrically connected to the third-party signal detection unit via other interface standards, and the third-party signal includes but is not limited to PCIe, USB, optical fiber, etc. The third-party signal detection unit 201 first detects the type of the modal input signal, and then the Ethernet conversion unit 202 retrieves the corresponding interface standard according to the type of the input signal to convert the corresponding modal signal into an Ethernet signal.

[0052] Furthermore, the communication module 20 also includes a signal rate control unit 203 and a voltage conversion unit 204. The signal rate control unit 203 is electrically connected to the Ethernet conversion unit 202 and is used to control the transmission rate of the third-party signal under different interface standards into the Ethernet signal; the voltage conversion unit 204 is electrically connected to the signal rate control unit 203 and is used to convert the transmission voltage based on the interface standard into a first preset voltage, which is the bias voltage corresponding to the Ethernet signal when transmitting data.

[0053] To implement communication functions, the communication module also includes an Ethernet signal output unit 205, whose first input end is electrically connected to the voltage conversion unit 204 to receive Ethernet signals converted from third-party signals, and whose second input end is electrically connected to an Ethernet input unit 80 to directly receive Ethernet signals sent by the Ethernet signal input unit 80. This allows the Ethernet signals received from the Ethernet signal input unit 80 and the Ethernet signals received from the Ethernet conversion unit 202 to be transmitted to the PSE module 30. By converting multiple input signals, such as PCIe, USB, and optical fiber, into Ethernet signals, this module fills the gap in implementing multimodal signal communication based on PoE. Using multimodal signal transmission for control, synchronization, and data communication can avoid or mitigate signal electromagnetic interference, alleviate or resolve the unstable performance of Ethernet cable communication, and improve network robustness.

[0054] By way of example and not limitation, in this embodiment, the Ethernet conversion unit 202 is a chip, and the Ethernet chip is further connected to a filter circuit to filter out interference from other signals during the signal conversion process.

[0055] It should also be noted that the PSE module 30 further includes:

[0056] The power access unit 301 is configured to receive a power supply signal from the energy storage subunit to supply power to the PSE control unit 302 and the first POE unit 304 respectively.

[0057] The PSE control unit 302 is electrically connected to the energy storage subunit 1013 via a power access unit and is used to provide power to the Ethernet cable in accordance with the IEEE 802.3bt standard. It can detect powered devices (PD modules) with certain valid characteristics, determine the power requirements of the devices based on their classification, and provide power;

[0058] The first PHY unit 303 is used to provide the data link layer with a physical standard interface for transmitting the original bit stream. The physical layer is located at the bottom layer of OSI. The physical layer protocol defines the electrical signals, line status, clock requirements, data encoding and connectors for data transmission, providing the data link layer with a physical standard interface connection for transmitting the original bit stream.

[0059] Furthermore, the PSE device also includes multiple PD modules 40, and the PSE module 30 also includes a first POE unit 304, which is connected to at least one PD module load through an RJ45 interface 50. Specifically, the PD module 40 includes an MCU microprocessing unit 401, a drive unit 402 electrically connected to the MCU microprocessing unit 401, and an LED unit 403 electrically connected to the drive unit 402. The PD module also includes a second PHY unit 406 and a second POE unit 405. The second POE unit 405 and the first POE unit 304 are connected through an RJ45 interface 50. The RJ45 interface 50 receives the signal transmitted by the Category 5e cable to the PSE module 30, and its network port is connected to the PD module 40 to realize visible light communication, thereby controlling the PD module 40 to realize LED lighting. It can also be connected to a router and a control terminal to realize remote control and information interaction through the terminal device based on the Internet to realize intelligent dimming function.

[0060] Specifically, the MCU microprocessor unit 401 is connected to the second POE unit and is configured to send a control instruction to the driver unit 402 based on the received Ethernet signal. The driver unit 402 drives the LED unit to turn on according to the control instruction. The Ethernet signal input unit 80 is connected to the mobile terminal via a signal transmission module and is configured to receive the light intensity signal sent by the mobile terminal. Remote control and information exchange through the terminal device over the Internet can realize the intelligent dimming function.

[0061] In summary, the PSE device based on multimodal energy and signal input proposed in the present invention utilizes multimodal energy input for power supply, replacing the traditional method of relying solely on mains power. This significantly reduces the mains load, improves power supply stability, and saves energy. Furthermore, the use of multimodal signal transmission for control, synchronization, and data communication can avoid or mitigate electromagnetic interference, alleviate or resolve the unstable communication performance of Ethernet cables, and improve network robustness.

[0062] See also Figure 2 FIG. 1 is a flow chart of a control method for a PSE device based on multi-modal energy and signal input according to a second embodiment of the present invention. The control method includes steps S01 to S04, wherein:

[0063] Step S01: The charge and discharge controller obtains current power information of the energy storage subunit at a first preset time interval, and determines whether the current power information is lower than a first preset power threshold;

[0064] In order to give priority to third-party energy supply, minimize the load on the mains, and achieve the purpose of saving energy consumption, the charge and discharge controller will continuously monitor the current power information of the energy storage sub-unit in real time to determine whether its real-time power is lower than the first preset power threshold. The purpose of setting the first preset power threshold is to monitor whether the power value of the energy storage sub-unit is at a low level. Since the first preset power threshold is related to specific usage requirements, in this embodiment, the first preset power threshold is not specified in detail.

[0065] Step S02: If the current power information is lower than a first preset power threshold, controlling the third-party energy conversion sub-unit to be turned on;

[0066] It should be noted that when it is detected that the power of the energy storage subunit is low, in order to ensure that the PSE device can continue to supply power, the charge and discharge controller will control the third-party energy conversion subunit to turn on, that is, start charging the energy storage subunit.

[0067] Step S03: calculating a power change value of the energy storage subunit according to the power information of the energy storage subunit at adjacent moments, and determining whether the power change value is less than zero;

[0068] In the process of using third-party energy to preferentially charge the energy storage subunit, the charge and discharge controller will also monitor the change in the power of the energy storage subunit to determine whether the power of the energy storage subunit is increasing when charging with the third-party energy.

[0069] Step S04: If the power change value is less than zero, the mains complementary control subunit is controlled to be turned on, so that the mains complementary control subunit inputs a DC voltage to the energy storage subunit.

[0070] It can be understood that if the monitored power change value is less than zero, it means that the power of the energy storage sub-unit is still decreasing when charging with a third-party energy source. Based on this, in order to maintain a stable power supply for the PSE device, the charge and discharge controller will control the complementary controller sub-unit to turn on, so that the third-party energy and the mains power can jointly charge the energy storage sub-unit.

[0071] It should be noted that the control process will start monitoring when the lighting system is in use. By setting a first preset time to continuously monitor the power status of the energy storage sub-unit in real time, it can be determined whether the power of the energy storage sub-unit is low, so as to give priority to controlling the third-party energy for charging. At the same time, the real-time changes of the energy storage sub-unit will be calculated based on the power information of the energy storage sub-unit obtained at adjacent moments. If it is found that the power of the energy storage sub-unit is still decreasing during the charging process using the third-party energy, it is necessary to control the mains complementary control sub-unit to start up to supplement the charging of the energy storage sub-unit. By precisely controlling the multi-modal power supply module, the priority use of third-party energy for power supply can be achieved. Only when the third-party energy is insufficiently charged will the mains power be controlled to cooperate in power supply, which greatly reduces the load of the mains power, saves energy consumption, and is conducive to green environmental protection.

[0072] In addition, it is important to note that Figure 3 In order to achieve multimodal communication, the control method of the communication module in this embodiment further includes:

[0073] Step S101: The third-party signal detection unit detects whether its input interface has an Ethernet input signal;

[0074] Step S102: If there is an Ethernet input signal, disable the input functions of other signals to give priority to using the Ethernet pass-through mode to transmit the input signal to the Ethernet signal output unit;

[0075] Step S103: If the third-party signal detection unit detects that there is no Ethernet input signal on its interface, it detects the input type of other signals and transmits the signals to the Ethernet conversion unit according to the input type of other signals and the signals so that the input signals are encoded and reassembled according to the external network protocol;

[0076] Step S104: After the input signal is reassembled, the signal rate control unit detects whether the acquired interface data signal rate is greater than a preset transmission rate;

[0077] Step S105: If the interface data signal rate is greater than the preset transmission rate, the signal rate control unit performs data buffering on the input signal to output the input signal at the preset transmission rate;

[0078] Step S106: If the interface data signal rate is greater than the preset transmission rate, the signal rate control unit transmits according to the current interface data signal rate;

[0079] Step S107: After receiving the input signal, the voltage conversion unit converts the input signal according to the Ethernet signal standard and transmits the converted signal to the Ethernet signal output unit.

[0080] By realizing the transmission of multimodal signals and then realizing data communication, the PSE module and visible light communication are combined to avoid or reduce the electromagnetic interference of the signal, alleviate or solve the defect of unstable communication performance of Ethernet cable, and improve the robustness of the network.
